>> 1000 USD bills exist but are very rare. Technically, $500, $5000, and $10000 also exist in private collections. They were last printed in 1945, and stopped being issued in 1969. They're worth far more than their denomination to collectors, understandably. Also, technically, $100k bills exist. They, however, were printed during the Great Depression and intended solely for transfers between federal reserve banks, and were never circulated. It's illegal to hold them privately, though there are some museums and things that have one.
